The third day was miserable. Woke with a headache and felt like I was coming down with a cold, and a little dizzy at times. It was pretty bad. I just wanted to go back to bed and stay there for the rest of the day. However, I expected that. From all that I read the first 3 days are the worst. So true. The 4th, which is today, was ok. No headache, and I felt amazingly alert. Hopefully I’m on the other side and It will be clear sailing now. The great part is that I am losing a pound a day. This is awesome!
